Kill Bill is the fourth film by writer-director Quentin Tarantino. Originally conceived as one film, it was released in two separate volumes (in Fall 2003 and Spring 2004) due to its running time of approximately four hours. The movie is an ambitious, epic-length revenge drama, with homages to earlier film genres, such as Hong Kong martial arts movies and Italian "Spaghetti Westerns"; an extensive use of popular music and pop culture references; and deliberately over-the-top bloodletting. Stars of the films include Uma Thurman, David Carradine, Vivica A. Fox, Lucy Liu, Michael Madsen, Daryl Hannah, Julie Dreyfus, Michael Parks, Sonny Chiba, Gordon Liu, Chiaki Kuriyama and Samuel L. Jackson.
